Evidence indicates higher prevalence of obesity in rural American youth. The present study evaluates the growth status and estimates the prevalence of overweight and obesity among rural school children in Texas.
Heights and weights were measured in a sample of 1,084 school youth (545 males, 539 females) 5-19 years of age, in rural north central Texas in 2010. body mass index (BMI) was calculated. Growth status was plotted relative to US reference data. Weight status (underweight/thin, overweight, and obesity) was classified relative to age- and sex-specific Centers for Disease Control (CDC) and International Obesity Task Force (IOTF) criteria. Concordance of classifications was evaluated.
Mean heights of the rural children approximated reference medians, while median weights exceeded reference medians and approximated 75th percentiles with increasing age. Median BMIs of boys and girls were below the 75th percentiles except among late adolescent girls. Prevalence of underweight/thinness was low (<4%). Overweight approximated 20% among boys 6-11 years and 16% among boys 12-19 years with CDC criteria; the opposite was apparent for obesity, 6-11 years, 16%, and 12-19 years, 20%. Approximately, equal percentages of boys in both age groups were classified overweight (∼21-22%) with IOTF criteria, but almost twice as many older (15%) than younger (8%) boys were classified obese. Overweight was less prevalent (∼5%) but obesity more prevalent (∼5%) with CDC compared to IOTF criteria, but both were less prevalent among younger than older girls.
Prevalence of overweight and obesity among rural Texas school youth was comparable to national estimates for 2007-2008. The results highlight a need for programs aimed at preventing unhealthy weight gain and/or weight reduction given the tendency of obesity to track from childhood into adulthood and potentially negative health consequences of obesity.

有证据表明,美国农村青少年的肥胖症患病率较高。本研究评估了德克萨斯州农村地区学童的生长状况,并估计了超重和肥胖的患病率。
2010 年,在德克萨斯州北部农村地区,对 1084 名 5-19 岁的在校青少年(545 名男性,539 名女性)进行了身高和体重测量。计算体重指数(BMI)。根据美国参考数据绘制生长状况图。根据年龄和性别特异性疾病控制和预防中心(CDC)和国际肥胖工作组(IOTF)标准,将体重状况(体重过轻/消瘦、超重和肥胖)分类。评估分类的一致性。
农村儿童的平均身高接近参考中位数,而中位数体重则随着年龄的增长而超过参考中位数并接近 75 百分位。除青春期后期女孩外,男孩和女孩的 BMI 中位数均低于 75 百分位。体重过轻/消瘦的患病率较低(<4%)。根据 CDC 标准,6-11 岁男孩和 12-19 岁男孩的超重率约为 20%,肥胖率约为 6-11 岁,16%和 12-19 岁,20%。用 IOTF 标准,两个年龄组的男孩超重比例大致相同(约 21-22%),但肥胖比例几乎是年龄较小(8%)男孩的两倍(15%)。与 IOTF 标准相比,CDC 标准下超重的比例(约 5%)较低,但肥胖的比例(约 5%)较高,但在较年轻的女孩中,超重和肥胖的比例均较低。
德克萨斯州农村地区学童的超重和肥胖患病率与 2007-2008 年的全国估计值相当。这些结果突出表明,需要开展旨在预防体重不健康增长和/或减肥的计划,因为肥胖症有从儿童期延续到成年期的趋势,而且肥胖症可能会对健康产生负面影响。美国人类生物学杂志,2013 年。©2012 年威利期刊公司
